The company I am captain of had a Criterion, second hand unit. I think it was owned by a company named Donahue out of Scranton, Pa. That's who purchsed our 1966 Cadillac, in 1975. They kept the Cadillac, till 1978, when they purchased a stock unit Dodge van. Going by the minutes, it was in pretty rough shape. The storage box on top, according to our neighbor, who was an EMT at the time held two scoops and a metal backboard, and it flew off one evening, destroying the box and everything inside. They had a demo ambulance three days later and bought it on the spot. She said the Criterion was stripped of its lights, wires, siren, etc; and sold for scrap. The junk yard said it was crushed years ago. But we had all the lights till just a couple years ago. Someone put a whole closet full in a dumpster. That's a damn shame right there. The siren, though, we still have that. I used it have it in my SUV, but it's really big, clunky, and would make strange noises, instead of the wail, yelp and hi-lo.
